\VILLIAM GORDON, OF BOSTON, MASSACHUSETTS, ASSIGNOR, BY DIRECT TO ARTHUR FULLER, TRUSTEE, OF SAME SOLE-EDGE-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 364,585, dated June 7, 1887.

Application filed January 8, 1887. Serial No. 223,725.

To all whom it may concern.-

Be it known that I, WILLIAM GORDON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole-Edge-Burnishing Machines, of which the following is aspecification.

' .Thisinvention relates to boot and shoe sole edge machines; audit consists in the improvements hereinafter described and set forth.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of the machine. Fig. 2 represents a side elevation of the same. Fig. 3 represents an enlarged section on linear 00, Fig.

i 1. Fig. 4rep'resents an enlarged section on line 3 y, Fig. l;

The same letters of reference indicate the same parts in all the figures.

In the drawings, (It represents the frame or pedestal of an edge-burnishing machine. 1) represents the driving-shaftjournaled in bearings at the upper part of said pedestal. 011 said shaft are formedtwo eccentrics, d (I, having their centers at diametrically opposite sides of the center of the shaft. On said eccentrics are .swiveled blocks 9' g, which are fitted to slide in slots it, formed in the upper ends of two levers, it. Said levers are mounted, respectively, on studs j j, affixed to the pedestal a, and are socketed at their lower ends to receive the shanks k of sole-edge-burnishing tools 70', each lever having a tool. The shanks of said tools are adapted to slidein said sockets, and are pressed downwardly therein by springs m as far as pins 12 on said shanks, abutting against stops in the sockets, will permit. The tools are thus adapted to yield, as will be readily seen.

The rotation of the driving-shaft eccentrics d d to oscillate the levers t i and reciprocate the burnishingtools 70 7c simultaneously in opposite directions. The lever t" is bent or offset, as shown in Fig. 2, so that while the upper ends of the levers vibrate in difi'erent planes, to accommodate the two eccentrics on the driving-shaft, their lower ends, having the burnishingtools, vibrate in the causes the (No model.)

same plane, and therefore act simultaneously on a sole edge held against them by the operator. 1

It will be seen that the two tools, acting simultaneousl y, burnish more rapidly than a single tool, the work performed in a given time being nearly equal to that performed bytwo machines having only one tool each, while only one operator is required.

To prevent the burnishing-tools from swiveling or turning too loosely, I provide the levers t with downwardly-projecting lips Z, which are close to the rear sides of the tools and prevent the tools from turning, so that their lips will stand across the line of their movement. 1

rrepresents a lever pivoted to cars on the outer side of one of the levers t, and having on'its lower end a socket, which receives the shank of a burnishing-tool, 1", formed to act on the shank-cdge of a sole, the tools 7c 70 being formed to act on the fore-part edge. The lever r is normally held in theposition shown in Fig. 4, so that it will not be in the way during the fore-part-burnishing operation, by a spring, 8. the tool T, he engages the shank-edge with the longer lip of said tool and draws the latter outwardly to a convenient distance from the lever When the operator desires to use '5. After the shank-edge is burnished the springs forces the tool a" inwardly and prevents it from swinging loosely.

I claim 1. In a sole-edge-burnishing machine, the combination of the supporting-frame, the driving-shaft journaled therein and having two oppositely-projecting eccentrics, d I, the toolcarrying lever z, independently pivoted on a center, j, and engaged at its upper end with leverst' i, arranged with their tools in the same plane, and their operating mechanism, the name to this specification, in the presence of combination, with one of said levers, of the two subscribing witnesses, this 24th day of lever r, pivotally connected with the lever i, December, A. D. 1886.

and having a shank-edgebnrnishing tool ar- WILLIAM GORDON. 5 ranged at one side of the plane in which the Witnesses:
